Product: Pavilion p7-1443

Operating System: Microsoft Windows 8 (64-bit)

A friend of my parents recently gave them this PC without any background and they gave it to me. When trying to boot it up, after a few seconds it just gives 6 long beeps alongside 6 orange flashes of the power LED. After that it goes back to blue, and nothing is displayed on the screen.

After a lot of looking around people seem to say it is a graphics card issue, but this PC does not have a graphics card and never did (warranty seal was still on it when I got it). I have tried two different graphics cards in it (HD 6950 and GT 520) and both graphics cards along with integrated graphics still give the 6 beeps.

Some sources say it's the Secure Boot that needs to be disabled in the BIOS, but I can not get into the BIOS. Even by pressing F2 or F10 on startup, it still has the same result of going straight to the 6 beeps and blank screen.

I have tried reseating the CPU (i3-3220), swapping it out for an i5-2500, trying different sticks of RAM, and different hard drives. Still nothing, every time booting up it gives the 6 beeps.

You are correct that you can't add a non-HP video card (one that would have come with that PC as an option), unless you go into the BIOS, enable legacy mode and disable secure boot on any HP PC that comes with W8 or newer from the factory.

Apparently the onboard Intel graphics adapter on the motherboard has failed, which is why you are getting the 6 beep code with no graphics card installed.

Here is the parts list for that model and unfortunately, there are no optional add on HP graphics cards listed, so I can't tell you which one might work.
